Specification forming part of Letters Patent No. 174,321, dated February 29, 1876; application'filed i February 7, 1h76.

To all whom it may concewnv Like letters of reference in all the figures Bel it known that I, STEPHEN P. indicate the same parts. 'l TASKER, ofthe city and county ot' Philadel- A, A1, and A2 are horizontal plates, which Y phia, in the State of Pennsylvania, have inf have bearings for the journals of the drivingvented `a new and useful Machine for PushingD shaft B and shafts C and C. On the shaft Metallubes and Skelpsinto and through a (lis the-wi'ld-cat wheelD, for propelling the Furnace, of which the following isa full 'and endless chain F, and on 'the shaft C is placed -exactdescrption, reference being had to the the chain-carrying wheel D. The plates are accompanying drawings. supported at one end by the wall H, which is My inventlon consists of the following parat one end of the furnace and at the other end ticulars: A n endless chain is placed on a wildby the'wall l. This wall is open below for the cat or other`wheel,and with said chain is conpassage of the tube or skelp. The general nected a'slide, which has. an arm for pushing arrangement for the support of the revolvingthe tube or skelp forward. The arm is'hinged lshafts is given merely for illustration. With tothe slide to admit of it being adjusted so as the bottom edges of the plates A1 and A2, to be in line with either opening of thefurbetween which the chain F moves, is connace. It is held in its adjusted position by nected the slide J, which is operated by means any suitable device. The arm has a projecof the chain. K is an ar'm of the slide. It is tion to receive the rear end ofthe tube or hung thereto by means of the pino. The arm skelp, the forward end being placed in the has a'projection, b, which serves for a rest for furnace-opening. `Connected with the arm is the rear end of the tube or skelp Z, the front a rod which projects forward and has at its end of which is placed in one of the openings forward end a crotch for` the connection with d in the end of the furnace. The pivotal con the rearend of the tube,'to Vfinish pushing it nection of the arm with the slide J admits of into the furnace' after the termination of the its being so adjusted as-to be in line with either action of the arm. On, the wild-cat shaft is opening of thefurnace. When adjusted it is 4placed a'double-cone clutch whichconnects held in place by 'means of the pin e, which is by means of a lever alternately with two bandvplaced in one of the holes f.' When the mawheels which are inline with two other wheels chine is used with afurnace having a singlev on the drivingfshaft, whereby two belts are opening, the arm K may have a xed connec` used alternately-(one being loose) for giving tion with thel slide J. On the driving-shaft B a forward and reverse movement to the chain are' placed pulleys L and L', and on the shaft for pushing the tube or skelp into the furnace C, which is provided with the wild-cat Wheel and returningthe carrying-arm to its position D, are loose pulleys L2 and L3, and with the for pushing forward another skelp or tube. pulleys L and L2 are connected the direct belt I prefer using the friction-clutch above men- Mfa'nd with the pulley Lland L2 the crosstioned instead of an ordinary clutch, so that belt M', for giving alternately a forward moin case of accident the wheels will slip and tion to the arm K, to push the tube or skelp prevent damage. For pushing the tube or into the furnace, and' a' reverse motion for skelp into the bending or welding rolls I use bringing the arm back to its starting-point a rod of convenient.shapeconnectedwith the ready for the Inovement of the next tube or abovementionedcarrying-arm 5 and'for draw skelp. 0n the shaft G, forfasteuing the puling them ont ofthe furnace at the sameend leysl L2 L3, is the double-cone clutch, N, they enter it I apply tongs connected with .operated by means of' the lever O, forconsaid arm. necting the clutch respectively withv the said In the accompanying drawings, Figure l pulleys L2 and L3, for changing the motion of is a plan view of my machine with a horizon-V the chain, so as at the proper time to move tal section through the conical clutch and the arm forward to pushthe tube or skelp into band-wheels connected therewith. Fig. 2 is the furnace, or b y a reverse motion to bring it a side elevation of the machine. Fig. 3 is an to its position for pushing another tube or end elevation of the same. skelp forward. As the tube or skelp cannot be pushed all the way into the furnace by the arm K,'I use the rod P for completing the operation. The rod is hung at its rear end to the arm K by means of the joint-pin g. Its forward end has a crotch, h, which is connected with the end of the tube or skelp after a reverse-movement isgiven tothet'chain tobringv the crotch back to the right position to make the connection. of the tube into the furnace is completed the movement of the chain is again reversed for pushing forward another tube or skelp. By

employing a different device for pushing the tnb'e or skelp into the fnrnace,a continuous motion might be given to the chain F. But, as it is sometimes necessary to draw the tubes or skelps out of the furnace at the same end they go in, I prefer the' reciprocating movenient to the chain. When they are so drawn out I use a pair'o tongs' connected with thev arm K; For pushing the tube or skelp through the furnace into the' lbending or welding rolls, I use-1 a bar of any convenient shape attached to the arm K. It willreadily .bessen that in place of the endless'chain other devices-'may be used, such as a metallic'band, wire rope, Ste. arm K suitablestands may be used for laying thetube or skelp onand having the lower end And when the-pushing.

And instead of the projecting' of the-arm bearing against 'their rear ends. I prefer arrangingthe endlesslchain and parts connected therewith overhead, as shown in the drawings, instead of below, so as to have them out of the way; in which case the tube or skelp would ylieon the chain F, as shown 4by dotted linesin-Fig. 2.

We claim as my invention- 1..'Ihecombination1of the endless chain F with the double acting clutch N and pulleys L2 and L3, for giving a reciprocating motion to the chain, substantially as set forth.

y 2'. Thesli'de J, havinga'n arm,-K, in combi- Y nation with the endless chain F, for the movement of a tube or skelp, substantially as set forth.

3. The arm K,.hin'ge'd tothe slide J', and

adjustable by meansof' the pin eand holes f,

orother suitable: device, substantially as set forth.

\ 4:. The pnshingfro'd'P', having a crotch, h', at its'forward end, in combination with the arm K, substantially asandY for the purpose set.
